Discovery reveals a reversible magnetic field around a fast radio burst for the first time
快速射电暴 可逆磁场 无线电波闪光
2023/5/15
An international team of researchers has revealed new evidence on the nature of mysterious fast radio bursts (FRBs) – objects in space that produce brief, intense flashes of radio waves from distant g...
Study of infrared scintillations in gaseous and liquid argon - Part I: methodology and time measurements
Near infrared scintillations in noble gases and liquids Electroluminescence in noble gases Geiger-mode APDs
2012/4/19
A methodology to measure Near Infrared (NIR) scintillations in gaseous and liquid Ar, using Geiger-mode APDs (GAPDs) sensitive in the NIR and pulsed X-ray irradiation, is described. This study has bee...
High Bandwidth Pickup Design for Bunch Arrival-time Monitors for Free-Electron Laser
High Bandwidth Pickup Design Bunch Arrival-time Monitors Free-Electron Laser
2012/2/29
In this paper, we present the design and realization of high bandwidth pickup electrodes with a cutoff frequency above 40 GHz. The proposed cone-shaped pickups are part of a bunch arrival-time monitor...

String theory topology and spacetime significant progress High Energy Physics Theory
2011/8/17
Abstract: String theory has transformed our understanding of geometry, topology and spacetime. Thus, for this special issue of Foundations of Physics commemorating "Forty Years of String Theory", it s...
Starting from the universal entropy bounds suggested by Bekenstein and Susskind and applying them to the black-body radiation situation, we get a cut-off of space x ≥ lP with ≥ 0.1. We go further ...
Time duration of the parametric x-ray radiation
X-rays, PXR, dynamical diffraction, femtosecond electron bunches
2011/8/31
Time evolution of the parametric X-Ray radiation, produced by a relativistic charged particle passing through a crystal, is studied. The most attention is given to the cases when the radiation lasts m...

Measurements of time-dependent CP asymmetries in $B \to D^{*\mp} \pi^{\pm}$ decays using a partial reconstruction technique 。
A central theme in cosmology is the perplexing fact that the Universe is undergoing an accelerating expansion. The latter, one of the most important and challenging current problems in cosmology, rep...
A commonly adopted relational account of time evolution in generally-covariant systems, and more specifically in quantum cosmology, is argued to be unsatisfactory, insofar as it describes evolution re...
Matrix Model for membrane and dynamics of D-Particles in a curved space-time geometry and presence of form fields
Matrix Model membrane dynamics D-Particles
2010/12/23
We study dynamics of a membrane and its matrix regularisation. We present the matrix regularisation for a membrane propagating in a curved space-time geometry in the presence of an arbitrary 3-form fi...
Scalar Field in Non-commutative Curved Space time
Scalar Field Non-commutative Curved Space time
2010/12/24
We will study the theory of scalar field in non-commutative curved space time (NCCST) with a percussionist who has been found by Mebaraki. In this paper, the motion equation of the scalar field will ...
We discuss alternatives to the usual quantization of relativistic particles which result in discrete spectra for position and time operators
